【推荐1】在密码学中,直接可以看到的是明码,对明码处理后得到的内容为密码.有人用26个英文字母编了一个密码表:
现有5个字母构成的密码单词,记5个字母对应的数分别为
.已知
;
,其中
,
,
;
是最大的负整数;
;
是方程
的解.请你破译此密码,写出这个单词.
密码 | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() |
明码 | ![]() | ![]() | ![]() | 0 | 1 | 2 | 3 |
密码 | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() |
明码 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
密码 | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() | ![]() |
明码 | 11 | 12 | 13 | 14 | 15 | 16 | 17 |
密码 | ![]() | ![]() | ![]() | ![]() | ![]() | ||
